Audio Analogue AAphono MM/MC Phono Stage Preamplifier

Audio Analogue AAphono Phono Preamplifier Delivers Precision Sound Quality for Vinyl Enthusiasts

The Audio Analogue AAphono phono preamplifier is a standout from Audio Analogue's PureAA line, built to elevate the vinyl listening experience for both casual enthusiasts and audiophiles. Its minimalist design and high-performance features align with Audio Analogue’s core philosophy of simplicity and excellence. Crafted for compatibility with various turntables and cartridges, this phono preamp provides both Moving Magnet (MM) and Moving Coil (MC) support, ensuring a clean and dynamic signal path for vinyl records of any type or quality.

Advanced Circuit Design Achieves Precise RIAA Equalisation

The AAphono preamplifier uses a dual operational amplifier (op-amp) configuration to divide the total gain, creating a highly accurate response to the RIAA curve. This setup allows each amplifier to work with minimal deviation, enhancing the overall audio fidelity with remarkable precision. Only high-quality, low-tolerance components are used in parallel to reduce error rates, allowing the AAphono to achieve an exceptional frequency response of +/- 0.25 dB from 10 Hz to 20 kHz, thus maintaining musical integrity across all frequency ranges.

Subsonic Filtering and Power Supply Isolation

A selectable subsonic filter within the AAphono prevents large low-frequency oscillations, which can be caused by slight undulations in vinyl records. By placing the filter between the first and second amplifier stages, Audio Analogue ensures that even the most dynamic bass passages remain crisp, avoiding any signal saturation that could distort playback. Furthermore, the power supply is meticulously designed with three separate toroidal transformers: one dedicated to the control section, one for the right analog channel, and one for the left analog channel. This isolation, coupled with extensive power supply filtering, prevents noise interference and keeps grounding paths discrete for a purer, quieter listening experience.

Customisable Input Settings for MM and MC Cartridges

The AAphono is designed for versatile cartridge compatibility, offering user-friendly controls for both MM and MC cartridge settings. For MM cartridges, users can adjust both the capacitance and input resistance, while MC cartridge users can set the input resistance alone. These adjustments are made via intuitive buttons positioned just behind the front panel, allowing precise calibration without any need for disassembly or intricate switch manipulation. This personalised configuration is preserved even when the unit is unplugged, providing a seamless return to the listener’s preferred settings with each use.

Sleek, Durable Design in Aluminium and Satin Black Finishes

Encased in an elegant, durable aluminium body, the Audio Analogue AAphono preamplifier is available in a natural aluminium or satin black finish, lending a touch of sophistication to any audio setup. The minimalist form factor (87x220x372 mm) and a manageable weight of 5.8 kg allow it to integrate seamlessly with other audio components while offering a stable, sturdy build that resists vibration and interference, further preserving sound quality.

Impressive Gain and Signal-to-Noise Ratios for Both MM and MC Modes

The AAphono delivers impressive gain figures of 40 dB for MM cartridges and 65 dB for MC cartridges, providing optimal signal boosting tailored to cartridge type. With a signal-to-noise ratio (SNR) of 85 dB in MM mode and 65 dB in MC mode, this phono preamp captures the nuances of vinyl records without adding unwanted noise, ensuring each track is heard with the clarity and warmth intended by the recording artist.

The Audio Analogue AAphono brings a rare blend of high-quality sound, easy calibration, and refined design, making it an exceptional choice for vinyl enthusiasts seeking superior audio performance and aesthetic appeal in one sophisticated unit.
